Title: Improved method of producing milk powder preparations
IPC: A23C1/04
Filed: 1937-05-24
Abstract: A milk powder preparation having improved keeping qualities is obtained by separating the cream from milk, spray drying the two liquids and subsequently mixing the powders obtained, the two liquids being adjusted to different hydrogen ion concentrations such that the powders when dissolved in water neutralize each other to the desired extent and exhibit as a whole acidity corresponding to pH 6,4-6,6 which is the normal value for milk.  The cream is preferably adjusted to a pH below 5,5 or above 7 while the skim-milk is adjusted to a pH of above 8 or below 7 respectively.  The pH value is increased by adding sodium bicarbonate &c. and decreased by adding acidic materials or by developing acid by fermentation.  The liquids may be pasteurized, e.g. by heating to 75 DEG  C. for less than 30 secs., before drying. The skim-milk may be concentrated at not above 55 DEG C., preferably 40 DEG  C., prior to drying.  The liquids may be dried in separate plants, or in one plant in which there are two atomizers, one for each liquid, or one atomizer having separate atomizing elements, wheels, turbines or discs, each with a separate inlet for the liquid, may be employed.  Fat soluble vitamin, cystine and other anti-oxidants may be added to the cream before drying.

Title: Improvements in or relating to the manufacture of interpolymers of styrene with unsaturated fatty acids and derivatives thereof
Inventor: SLEIGHTHOLME JOHN JOSEPH
IPC: C08F212/14
Filed: 1948-05-28
Abstract: Interpolymers of styrene or alkyl or halogen nuclear-substituted styrene, with one or more unsaturated fatty acids or the partial ester or esters thereof are made by heating, e.g. below 250 DEG  C. a mixture of the components, optionally dissolved in a volatile solvent, with or without superatmospheric pressure, in the presence of 1/2 to 5 per cent by weight of sulphur based on the fatty acid radicles.  In a modification the fatty acid is fully esterified and the interpolymer saponified to the fatty acid or acids, or alcoholysed, e.g. in the presence of ethylene glycol, glycerol, sorbitol or pentaerythritol to yield partial esters.  Styrenated oil-modified alkyd resins may be prepared by heating the interpolymers with polybasic acids, e.g. phthalic acid and polyhydric alcohols, e.g. glycerine.  Specified fatty acids are those derived from linseed and castor oil; specified partial esters are mono- or di-glycerides of linseed oil; specified fully esterified fatty acids are linseed oil, china wood oil and dehydrated castor oil.  The interpolymers may be converted into soaps and the alkali metal and ammonium soaps used as emulsifying agents.  The styrenated oil-modified alkyd resins may be compounded with pigments, solvents, e.g. xylol, driers such as cobalt and lead naphthenates, water and stabilizing agents such as glue and casein, and used as coating or impregnating compositions or printing inks.  Specifications 573,809, 573,835 and 616,044 are referred to.

Title: Improvements in or relating to apparatus for measuring fluid pressures
IPC: G01L7/00
Filed: 1922-05-26
Abstract: 202,435. Barnes, J. W. May 26, 1922. Elastic-diaphragm pressure gauges.-Comprises a method of or means for eliminating hysteresis or lag in fluid-pressure measuring instruments and consists in coupling a plurality of resilient chambers together in such manner that one or more controls the pressure applied to others and the hysteresis occurs in opposite directions, the indicating means being connected to a point in the system which moves positively for changes of pressure, but does not move for change of hysteresis. The invention is described as applied to an altimeter for air-craft. Two similar aneroid chambers 1, 2 are mounted on a base 3. A spring 6 having a fulcrum on a knife-edge 7 on a wedge-piece 8 engages at the ends under knife edges 5, 4 carried by the chambers 1, 2, the position of the fulcrum 7 is such that the spring exerts unequal efforts on the two chambers. A lever 9 rests at one end on the chamber 2 by means of a knife-edge 11 and at the other end by means of a roller 10 on the chamber 1. Due to hysteresis or lag only, the lever 9 tends to turn about a point such as 13, while due to variations in pressure only, the lever 9 tends to turn about some point to the left of the point 13. The indicating means are thus actuated from the point 13 which has no movement due to lag, and the mechanism comprises a lever 14, a linkage 16, and chain operating a pointer 17. The position of the point 13 is determined by trial.

Patent GB-1095197-A (GB)
Title: Electrolytic recovery process
IPC: C25C1/20
Filed: 1965-04-09
Abstract: Metal of which a salt is being dissolved in a processing solution from a succession of travelling articles passing into and out of the solution, is recovered by electrolyzing the solution or a continuously changed fraction of it in order to deposit the metal at substantially the same rate as it is dissolved in salt form, the electrolysis current being initiated successively by the passage of the articles and being interrupted after a fixed period less than the interval between the passage of any two successive articles.  As described the method is applied to the recovery of silver from a photographic processing (fixing) solution through which pass a succession of hangers supporting photographic material, entry of each hanger into the bath closing a switch to enable a motor to drive a cam-operated time switch which opens before the next hanger enters the processing bath.  The silver recovery may be effected either in the processing tank or in a separate tank fed by over-flow from it, a pump returning liquid from the electrolysis tank to the processing tank.

Abstract: 438,665. Exchange systems. SIEMENS BROS. & CO., Ltd., Caxton House, Tothill Street, Westminster, CHITTENDEN, P. A., 22, Sandtoft Road, Charlton, and CRUTCH, L. S., 15, Mundania Road, East Dulwich, both in London. May 22, 1934, No. 15286. [Class 40 (iv)] [See also Group XL] A signal receiver particularly for telephone systems using alternating current for signalling purposes, comprises an input transformer 4, 5 with a third winding 6 shunted by a series resonant circuit 8, 9 to exclude an undesired frequency and by a capacity or inductance 10 forming with the circuit 8, 9 a parallel resonance circuit at a frequency to which the receiver is required to be specially sensitive. To increase the sensitivity of the receiver to the desired frequency the anode and grid circuits of a valve thereof may be coupled by a circuit having strong retro-action at that frequency. The anode may be coupled by a condenser to the grid end of winding 5. The invention is applicable to telephone systems using different frequencies for signalling in the two directions or to systems in which one frequency is used for calling and another for reply signalling. In systems of the last mentioned kind, two receivers are connected at both ends of the system, and during speech, both operate, but the operation of one renders the operation of the other ineffective. The Provisional Specification also describes a three-winding differential transformer in which the input is connected to centre taps on two windings which are connected at their ends by a circuit tuned to an unwanted frequency and by an impedance matching the tuned circuit at that frequency, the receiver being connected to the third winding. The transformer is thus balanced at the unwanted frequency.
